Just wanted to say Hello. Been watching this forum for a while now and picked up some good tips. Enjoyed being an Audi owner fo a few years now, had a mk1 TT Coupe (was in the TTOC), but afraid it had to go. (Family practicalities) Now got an A3 170pd Quattro Sport (no mods yet though). Its an 08 model and no problems with DPF. Pleased with car as a whole. Someone might be able to answer this question for me hopefully. In the boot next to the spare wheel is a black lid bolted down and covering what is the battery box on other models, why is this closed off on my model and what is in it?
